Transformation of MPEG-4 Contents for a PDA Device
نویسندگان
چکیده
We propose a transforming method of MPEG-4 contents in order to present the contents on PDA devices in this paper. The method reconstructs the mp4 file according to transforming a scene tree in MPEG-4 contents when the contents are authored. The method reduces the size of each object in a scene of the content for presenting it efficiently on the small interface of a PDA device, and transforms visual objects in the scene into geometry objects in order to reduce initial loading time and a size of the contents. And an original object is presented on a PDA device when the user clicks the substituted geometry object. The method was applied to a conventional authoring tool, so we could find that the method showed an efficient presentation of the contents on a PDA device.

An Efficient Player for MPEG-4 Contents on a Mobile Device
We describe an implementation of an efficient player for MPEG-4 contents on a mobile device. The player uses 3 adaptation methods in order to support high efficiency when it plays MPEG-4 contents. The adaptation methods are composed of a physical adaptation, an event adaptation, and a resource adaptation. The first adaptation resolves the physical difference between the authoring environment an...

متن کاملOntology Instance Matching based MPEG-7 Resource Integration
Heterogeneous multimedia contents are annotated by a sharable formal conceptualization, often called ontology, and these contents, regardless of their media, become sharable resources/instances. Integration of the sharable resources and acquisition of diverse knowledge is getting researchers’ attention at a rapid pace. In this regard, MPEG-7 standard convertible to semantic Resource Description...

To enhance the therapeutic effects of chemotherapy on malignant melanoma, paclitaxel (PTX)-loaded methoxy poly(ethylene glycol)-b-poly(ε-caprolactone) nanoparticles (MPEG-b-PCL NPs) that had their surfaces modified with polydopamine (PTX-loaded MPEG-b-PCL NPs@PDA) were prepared as drug vehicles. The block copolymer MPEG-b-PCL was synthesized by ring-opening polymerization and characterized by p...
